WEFT-REPLENISHING MAGAZINE FOR MULTEFSH'UITLE LOOMS.

Application filed July 19,

This invention relates to a magazine for holding reserve supplies ofweft for the different shuttles in a multi-shuttle loom. In such looms,it is sometimes desirable to use different types of bobbins in the samemagazine and these bobbins are not always of the same length or tipdiameter.

It is the general ob 'ect of our invention to provide an improvedconstruction in a weft replenishing magazine, by which said magazine isadapted to hold and deliver bobbins of substantially differentdimensions.

In the preferred form of the invention, we have shown a magazine capableof holding either relatively long bobbins of small tip diameter orrelatively short bobbins of a larger tip diameter.

Our invention further relates to arrange ments and combinations of partswhich will be hereinafter described and more particularly set forth inthe appended claims.

A. preferred form of the invention is shown in the drawings in which-Fig. 1 is a sectional side elevation of a magazine, showing the outer ortip-retainlng portion thereof;

Fig. 2 is an enlarged detail sectional plan view, taken along the line22 in Fig. 1;

Fig. 3 is a detail sectional elevation of one of the cradles, takenalong the line 3-3 in Fig. 1;

Fig. 4 is a partial side elevation of one of the cradles, looking in thedirection of the arrow 4 in Fig. 3;

Fig. 5 is an enlarged view of one of the give-way devices which supportthe tips of the bobbins during transfer; and

. Fig. 6 is a plan view of said device, looking in the direction of thearrow 6 in Fig. 5.

Referring to the drawings, we have shown a portion of a magazine frame10 supported on cross rods 11 which extend to and are secured in themain or head portion of the mag azine frame (not shown). The frame 10 isprovided with vertical ribs or flanges 12 forming guideways definingseparate compartments for the diiferent tiers of bobbins.

These flanges are of a special construction, as best shown in Fig. 2,and each flange is provided with an inner shoulder 13, so that twodistinct guideways are formed between each pair of flanges 12.

The inner and narrower guideway 14 is adapted to receive the tip of along and rela- 1926. Serial No. 123,277.

tively small bobbin B, and the wider outer guiding portion 15 is adaptedto receive the tip of shorter bobbin B of a larger tip diameter. Thebobbin B is of the type commonly used for worsted yarn,and the bobbin Bis of the type more commonly used for woolen yarn.

The butt portions of the bobbins are of the usual type and of the samesize, and the head end of the magazine is of the usual construction andis therefore not shown in the drawings.

ii/ 1th the construction described, it will be seen that eachoon'ipartment of the magazine may be used interchangeably for eithertype of bobbin B or B and that either or both of these bobbins will besecurely retained in position.

it is the usual practice to provide cradles 20 for supporting thelowermost bobbin in each compartment and for releasing a single bobbinupon indication of weft exhaustion. These cradles, as shown herein,arein general of the usual type but are of a special construction at thetip supporting portion, adapting them for use with both types ofbobbins.

Each cradle is provided with an outer flange portion 21 adapted toreceive and sup port the relatively small tip of a bobbin B and with aninner supporting portion 22 adapted to receive and support the tip of abobbin B. Each type of bobbin is thus centered and supported in the sameaxial posi tion and will be released and delivered for transfer uponindication of weft exhaustion.

The usual provision is made for yielding release of the tips of thebobbins during transfer, but the tipsupperting member 30 of the give-waydevice is of a special construction, particularly adapted to handlebobbins of different lengths and diameters, such as are indicated at Band B".

For this purpose, the member 30 is provided with the usualtip-supporting portion 3i and flange 82 by which a bobbin of the typeindicated at B will be supported and held from axial movement duringtransfer, in the usual manner. is have also provided a second orsupplementary supporting portion 33 adjacent the portion 31 andseparated therefrom by a shoulder 34. This portion 33 is so positionedthat it will cooperate with a shorter bobbin of larger diameter, such asB guiding the same accurately during transfer.

By the provision of these three changes in a weft carrier magazine,namely, the provision of guideways 12 forming vertical compartments ofdifferent widths for the tips of two different types of bobbins, and theprovision of cradles and give-way devices each having specific provisionfor adapting them to use with the same dillerent types of bobbin, wehave produced a ma azine in which these two different types oi bobbinsmay be used interchangeably, thus substantially increasing the range ofutility of the magazine.

Having thus described our invention and the advantages thereof we do notwish to be limited to the details herein disclosed otherwise than as settorth in the claims, but what We claim is 1.'In a 100m, a magazine framehaving guideways for the bobbin tips, said guideways having portions ofdifferent widths adapted to receive and center bobbins of ditferentlengthsand having tip portions of different diameters.

2. In a loom, a magazine frame having guideways for the bobbin tipsthereon, said guideways having an outer guiding portion of greater widthand an inner uiding portion of less Width, and said guideways beingadapted to receive and center bobbins oi? diliferent lengths and havingtip portions of different diameters.

3. In a loom, a magazine frame having a plurality of bobbin guidingmembers thereon extending across and at both sides of the two extremeend portions of the bobbin and ell'ective to closely engage anddefinitely position bobbins of ditferent lengths and having tip portionsof diil'erent diameters, and cradles co-operating with said guidingmembers. each having a portion ellective to closely engage the tip oi abobbin of one length and one tip diameter to advance said bobbin totransl'er portion, and having another portion at a less distance fromthe axis of said crznlle effective to closely engage the ii p of asecond bobbin of substantially less length and of substantially greatertip diameter to advance said bobbin to transfer position.

i. In a loom, a magazine frame having a plurality of bobbin guidingmembers thereon effective to laterally and definitely position bobbinsof different lengths and having tip portions of different diameters, andgiveavay devices for guiding said bobbin to transfer position, saiddevices having guiding portions at different elevations and separated byan abrupt shoulder, one of said portions being positioned to closelyengage a long and small tipped bobbin and the other portion beingpositioned to closely engage a relatively short and large tipped bobbin.

In testimony whereof we have hereunto aflixed our signatures.
